  1. Note: All models are estimated using unweighted least squares estimator with mean- and variance-adjusted test statistics. Models use delta parameterization. χ2chi-squared test statistics, df degrees of freedom, CFI comparative fit index, RMSEA root mean square error of approximation, SRMR standardized root mean square residual
